Duration: 1 1/2 hours/level
Casting Time: 1 round

Saving Throw: None

The creature receiving this spell is protected from normal extremes of cold or heat (depending on which application the priest selects at the time of casting). The creature can stand unprotected in temperatures as low as -30° F. or as high as 130° F.(depending on application) with no ill effect. Temperatures beyond these limits inflict 1 point of damage per hour of exposure for every degree beyond the limit. The spell is immediately cancelled if the recipient is affected by any non-normal heat or cold, such as magic, breath weapons, and so on. The cancellation occurs regardless of the application and regardless of whether a heat or cold effect hits the character (e.g., an endure cold spell is cancelled by magical heat or fire as well as by magical cold). The recipient of the spell does not suffer the first 10 points of damage (after any applicable saving throws) from the heat or cold during the round in which the spell is broken. The spell ends instantly if either resist fire or resist cold is cast upon the recipient.
